If going to a museum sounds like a helpful idea to you, but you don't want to leave the house, you might consider getting a coffee table book or another book with lots of pictures to explore and talk about that you can study with your daughter. Even if you don't want to buy one (I know that this kind of books can be expensive), the local library might have something on a subject both you and your daughter are interested in. You could ask her to go and get a suitable book or if she does not feel up to the task either send her and your husband for the book or only your husband. If you did the latter, you could also give him just an outline of what fields or subjects would be suitable for both of you and let him pick the book, so there's an element of surprise and neither you nor your daughter gets the advantage of consulting other sources like Wikipedia in advance.
Just a thought of how to eliminate the anxiety issue, but if you daughter is not interested in this kind of activity, you'll probably have to come up with something quite different anyway.
